Round the given decimal number to the nearest 0.000000001.
3* 10^(- 9)
Practice makes perfect
We want to round the given decimal number and write the result as the product of a single digit and a power of 10.
0.00000000305Let's start by rounding the given number to the nearest 0.00000000 1. Since the digit in the ten billionth place is less than 5, we will not modify the digit in the billionth place.
0.00000000 3 05 ≈ 0.00000000 3
Finally, we will write the above number as the product of a single digit and a power of 10.
To do so, let's first factor out 3.
